Refers to the movement or style evolving from Photorealism in the United States and Europe. Historically the term has often been used interchangeably with Photorealism. Hyperrealism may now be considered a separate idiom, particularly since the early 2000s. Hyperrealist works use photographic images as sources to make even more exacting renderings of subject matter. Hyperrealist painting and sculpture often incorporates narrative, emotive, or political content, unlike Photorealist works, which attempted to eschew subjectivity through precise rendering of the photographs themselves.
